2013-04-25[ms-cxxabi] Fix a number of bugs in the mangler.Peter Collingbourne
This includes the following fixes: - Implement 4 subtly different variants of qualifier mangling and use them in what I believe are the right places. - Fix handling of array types. Previously we were always decaying them, which is wrong if the type appears as a template argument, pointee, referent etc. Fixes PR13182.

2013-03-26[ms-cxxabi] Mangle vector typesReid Kleckner
Summary: The only vector types a user can pass from MSVC code to clang code are the ones from *mmintrin.h, so we only have to match the MSVC mangling for these types. MSVC mangles the __m128 family of types as tag types, which we match. For other vector types, we emit a unique tag type mangling that won't match anything produced by MSVC.

2013-03-20[ms-cxxabi] Fix assertion on unhandled function template arg typesReid Kleckner
This code was changed in r158376 to get template argument source info for better diagnostics, but the current code asserts for any kind of unsupported template argument before it can issue a diagnostic. This change goes back to the Itanium implementation of isTemplate() and puts the argument index into the diagnostic instead of a source location.

2013-02-18Replace TypeLoc llvm::cast support to be well-defined.David Blaikie
The TypeLoc hierarchy used the llvm::cast machinery to perform undefined behavior by casting pointers/references to TypeLoc objects to derived types and then using the derived copy constructors (or even returning pointers to derived types that actually point to the original TypeLoc object). Some context is in this thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056804.html Though it's spread over a few months which can be hard to read in the mail archive. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175462 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-13[ms] Make mangleIntegerLiteral less aware of exact type of the literal.Nico Weber
Integer literal mangling does not actually depend on exact type of the literal. This will simplify calling mangleIntegerLiteral when literal type is not known, for example, when sizes or offsets are mangled as integer literals. Also, call mangleNumber instead of directly printing mangled values of 0/1, to avoid this knowledge from being in multiple places.

2012-10-03While I'm here, resync a %select with the enum definition it selects on.Nico Weber
* nullptr used to be mapped to ERROR, now mapped to nullptr * integral was missing * expressions now have their own error message, so they won't reach this. Map them to ERROR. Note that clang usually crashes before emitting this diagnostic anyway (see PR13984), so this change alone doesn't have an observable effect. It makes the code more correct though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165095 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-07Plug a long standing memory leak in TemplateArgument.Benjamin Kramer
The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158150 91177308-0d34-0410-b5e6-96231b3b80d8
